How to Print on Custom Mylar Bags?

To print on Mylar bags, start by defining requirements and designing the artwork, selecting the appropriate printing method, preparing plates, printing on mylar film, laminating layers for protection, and finally cutting, forming, and quality-checking. The common methods used for printing include gravure printing for large-scale, high-detail production, flexographic printing for medium-volume cost-efficient runs, and digital printing for short runs with faster turnaround. The cost of printing on mylar bags typically ranges from USD 0.08 to USD 1.50 per bag, depending on factors such as printing method, order quantity, material thickness, finishing options, and additional custom features like zippers or valves.

The 9 steps for printing on custom mylar bags are as follows:

1. Define Your Requirements
2. Create the Design
3. Choose the Printing Method
4. Prepare Printing Plates
5. Print on Mylar Film
6. Laminate the Material
7. Cut and Form the Bags
8. Perform Quality Checks
9.  Ship and Distribute 

1. Define Your Requirements

Start by clearly deciding the size, shape, and functional role of your Mylar bags within the supply chain. For example, stand-up bags for retail display, flat pouches for shipping efficiency, or resealable mylar bags for repeated consumer access. Define film thickness in microns, with common ranges between 70 and 150 microns, and specify features such as ziplock closures, tear notches, hang holes, or degassing valves for coffee packaging. 

2. Create the Design

Develop your artwork using professional design tools such as Adobe Illustrator or CorelDRAW. Make sure your design is high resolution (300 DPI), uses CMYK color mode for accurate printing, and includes proper bleed and margin settings to avoid cutting errors during production.

3. Choose the Printing Method

Select the printing technique based on your order size and quality expectations. Digital printing works well for small batches and quick runs, while flexographic and gravure printing are better suited for large-scale production where consistency and cost efficiency are important.

4. Prepare Printing Plates

For bulk printing methods like flexography or gravure, custom plates or cylinders are created from your design. Although this step requires an upfront investment, it significantly reduces the cost per unit when producing large quantities.

5. Print on Mylar Film

The finalized design is printed onto rolls of Mylar film. During this stage, colors are applied in layers to achieve the desired look, and finishes such as matte, gloss, or metallic effects can be added to enhance visual appeal.

6. Laminate the Material

After printing, the mylar film, such as PET and BoPET, is laminated with additional layers to improve strength and barrier protection. The lamination process helps protect the contents from moisture, oxygen, and light while also giving the packaging a more premium feel.

7. Cut and Form the Bags

The laminated material is then cut into the required shapes and sealed to form bags. Additional features like zip locks, spouts, or hang holes may be added at this stage, depending on your specifications.

8. Perform Quality Checks

Manufacturers inspect the finished bags to ensure print accuracy, proper sealing, and consistent color quality. The step for quality check is essential to maintain product standards and avoid defects.

9. Ship and Distribute

Once completed, the custom Mylar bags are packed and shipped to your location or directly to retailers. Proper packaging and logistics ensure the bags arrive in perfect condition and ready for use.

What are the Common Methods for Printing Custom Mylar Bags?

The common methods for printing custom mylar bags include gravure printing, flexographic printing, and digital printing, each selected based on order volume, color precision, material structure, and turnaround constraints.

Gravure Printing

Gravure printing uses engraved cylinders to apply ink with high precision, making it suitable for large-scale production. It supports detailed graphics and smooth color gradients. Gravure printing is often used for food, cannabis, and coffee mylar packaging in high volumes. The initial setup cost is higher, but the per-unit cost is lower over time.

Flexographic Printing

Flexographic printing uses flexible plates and fast-drying inks to balance cost and quality. It is commonly chosen for medium-sized production runs of mylar packaging. The flexo printing method works well for snack packaging, spices, and pet food mylar bags. While efficient, it may not match the gravure printing method for mylar bags in fine detail.

Digital Printing

Digital printing applies designs directly from digital files without the need for plates, as this allows quick changes and shorter runs, making it ideal for testing or seasonal packaging. It supports variable data printing as well. However, the per-unit cost is usually higher compared to bulk methods.

What is the Cost of Printing on Mylar Bags? 

The cost of printing on mylar bags generally ranges from USD 0.08 to USD 1.50 per bag, depending on several factors. Pricing for printing varies based on printing method, order size, material layers, finishes, and closure features like zippers or valves. Large-volume methods like gravure reduce unit cost, while digital printing tends to be more expensive for smaller runs. Additional customization, such as complex finishes or thicker materials, can further increase the overall cost.
